1 RL-C2 radial slot outlet Air distribution systems DS E 04.1

2 Introduction The RL-C2 radial slot outlet with circular face generates a turbulent mixed flow. It is used for supply and return air distribution in comfort air-conditioning systems and has been optimised both acoustically and in terms of flow. Therefore, the slots, as the most important air distribution elements, were completely redesigned. The geometry was improved using state-of-the-art development and production methods such as CFD analyses and rapid prototyping, until the highest standards of room air flow and acoustics were fulfilled. This has also been confirmed in numerous laboratory measurements. The air outlet can be installed either flush with the ceiling or freely suspended and is available in 4 different sizes. For special uses such as perimeters and corner areas of rooms the otherwise radially symmetrical air discharge can be individually adjusted using special covers. Design The radial slot outlet essentially consists of the air outlet element 1 with circular face and the blades 1a for radial air discharge. The air outlet element 1 is available not only with a circular connection box 2a for freely suspended, visible installation but also with a cubical connection box 2b for installation flush with the ceiling. The air is supplied via the connection spigot 3, which is available with and without volume flow damper 4. The volume flow damper can be adjusted from the room. The air is guided through the connection box 2 and the air outlet element 1 by blades 1a. After undoing the central fixing the air outlet element can be removed easily from below. The whole air outlet unit is suspended from fixing points 6 on the connection box. If used as a return air inlet, the blades 2 are removed 1) and on request the box is painted black internally. 1) optionally available with blades too 2) all blades opened; V A max and V A min are reduced by closing individual blades Table 1: Technical data and dimensions Size Volume flow rate 2) V A max m 3 /h V A min m 3 /h Discharge height m 2, 4, 2,7 4, Dimensions ATD ø E mm Circular connection box ø A mm C mm ø D mm H 1 mm 480 L 1 mm L 3 mm Cubical connection box B mm C mm ø D mm ø D 6 mm H 1 mm 4 H 2 mm L 1 mm L 2 mm Weight ATD kg 1,2 1,9 2,8 4,4 Circular connection box kg 2,9 4,4 7,8 11,6 Cubical connection box kg 4, 6,0,0 18,0 Max. temperature difference between supply and return air K K K K cooling mode (flush with ceiling) 10 cooling mode (freely suspended) +10 heating mode (<3 m) + heating mode (>3 m) ø A 6 C 2a 4x ø 9 4 L 1 3 ø D H 1 Key 1 Air outlet element 1a Blades 2a Circular connection 2b Cubical connection box 6 4x ø 9 2b 4 B C 3 Connection spigot 4 Volume flow damper Central fastening 6 Fixing points L DS E p L 3 ø D H 1 ø D 6 H 2 L 2 1 1a ø E Figure 1: Dimensions with circular connection box 1 1a ø E Figure 2: Dimensions with cubical connection box 2

3 Mode of operation The circular radial slot outlet generates turbulent mixing air flow with high-induction radial air jets. The discharge direction is horizontal. Due to the specially adapted blade geometry, the same face plate can be used for both flush and freely suspended installation. The air jet exits horizontally below the plate with high velocity. Due to the radial arrangement of the blades, centrifugal force carries the air to the outside far beyond the plate, even with the freely suspended installation. With the flush installation the Coanda effect causes the air jet to be attracted to the ceiling. The large spread of the air jets ensures high induction with the room air and therefore good dissipation of reduction momentum and temperature. Figure : Circular radial outlet element with circular connection box Figure 3: Jet characteristics of outlet installed flush with the ceiling DS E p Figure 4: Jet characteristics of outlet freely suspended from the ceiling Figure 6: Circular radial outlet element with cubical connection box Note For freely suspended installation we recommend limiting the temperature difference between supply air and room air (or return air) to 10 K. This enables stable horizontal air jets to be generated, even with low volume flows. 3

4 Adjustment of discharge direction Discharge direction and air flow rates The radial slot outlet can discharge the supply air horizontally in 4, 3 or 2 directions. For 4-way discharge all blades are open. If air discharge is required only 3-way, 2-way symmetrical, or 2-way asymmetrical, then several slots are to be closed as shown below. The air flow rate is thus reduced; the related factors can be read from the following table, by use of the following equation: V Red = V A F Table 2: Factor F for volume flow reduction Size Jet direction 4-way way way symmetrical way asymmetrical Adjustment of discharge direction Discharge direction Size 4-way Type 0 3-way Type 1 2-way symmetric Type 2 2-way asymmetric Type 3 DS E p Figure 7: Discharge directions obtained by closing several slots Discharge slots: open; closed 4

5 Comfort criteria 1) The outlet layout must comply with the maximum allowable indoor air velocities u in the occupied zone in cooling mode. The indoor air velocity depends on the cooling load that is to be removed from the room. The maximum specific cooling capacity q depends on the discharge height and the maximum allowable indoor air velocity u (Graph 1). Graph 1 enables the maximum specific volume flow rate V Sp max for cooling mode to be determined in relation to the maximum specific cooling capacity and the maximum temperature difference DJ max. The volume flow rate supplied to the room V Sp act may not exceed this value. Graph 2 enables the minimum centre spacing between two outlets to be determined on the basis of the maximum specific volume flow rate.
